I want to convert string to binary equivalent and binary to string

I want to convert the string to binary equivalent and then again convert the string to binary. I got the code for this

String='This is your sample hidden string.';
binar=reshape(dec2bin(String,8).',1,[])
reconver_str = char(bin2dec(reshape(char(binar+'0'), 8,[]).'))

but i getting the error

Error using bin2dec (line 55)
Binary string may consist only of characters 0 and 1

Error in convstrtobin (line 3)
reconver_str = char(bin2dec(reshape(char(binar+'0'), 8,[]).'))

can anyone please help me how to correct this error.

Note that your conversion will only work for char arrays that only contain characters with value 0 to 255. This is a very small subsets of the characters supported by matlab.

Characters in matlab are not 8-bit.

You forgot to subtract '0'

binar=reshape(dec2bin(String,8).',1,[]) - '0';
